BACKGROUND/AIMS Postoperative adhesions following abdominopelvic surgery may cause significant morbidity. In this study, the effect of different doses of methylene blue in the formation of adhesions and the role of allopurinol in revealing the possible mechanism of action was evaluated. METHODS Seventy five male Wistar-Albino rats weighing 200g-220g. were divided into five groups of 15 rats e...

the nanocomposites of poly (acryl amide-co-acrylic acid) with different contents of naazeolite were prepared using ammonium persulfate as an initiator and n, n′-methylenebisacrylamide as the crosslinker. the morphology was characterized by sem and the structure ofnanocomposite materials was studied with xrd and ft-ir that showed the interaction betweenporous materials and poly (aam-co-aac). the...

Case. We report a case of severe methemoglobinemia due to sodium nitrite poisoning. A 28-year-old man was brought to our emergency department because of transient loss of consciousness and cyanosis. He was immediately intubated and ventilated with 100% oxygen. A blood test revealed a methemoglobin level of 92.5%. Outcome. We treated the patient with gastric lavage, activated charcoal, and methy...

Human erythrocyte ghosts were chemically cross-linked with a family of bifunctional cross-linking reagents, imidoesters. Since the reagents are identical in their chemical structures, except for the number of methylene groups, they differ by that distance between the functional groups. The maximum distance is 4.9 A in dimethyl malonimidate, 6.1 A in dimethyl succinimidate, 8.6 A in dimethyl adi...

In this study, citrus pectin-derived, green, and tunable carbon microspheres with superior adsorption capacity and high adsorption rate, as well as good reusability toward methylene blue adsorption, were prepared by a facile hydrothermal method without any hazardous chemicals. The materials hold great potential for the treatment of methylene blue wastewater.

UNLABELLED BACKGROUND We aimed to minimalize operative complications by spraying of methylene blue stain on thyroid glands and the perithyroidal area. MATERIAL AND METHODS The intra-operative methylene blue spraying technique was used prospectively on a total of 56 patients who had undergone primary (not recurrent) thyroid surgery for a variety of thyroid diseases. Bilateral total thyroide...

fertilizer plant waste carbon slurry has been investigated after some processing as an adsorbent for the removal of dyes and phenols using columns. the results show that the carbonaceous adsorbent prepared from carbon slurry being porous and having appreciable surface area (380 m2/g) can remove dyes both cationic (meldola blue, methylene blue, chrysoidine g, crystal violet) as well as anionic (...

The influence of Tuftsin, the synthetic phagocytosis-stimulating tetrapeptide (L-threonyl-L-lysyl-L-prolyl-L-arginine), on the nitrous blue tetrazolium (NBT) reduction by human polymorphonuclear leukocytes was investigated. It was found that this substance increases the NBT reduction by approximately as much as endotoxin. Other tetrapeptides do not share this property. When Tuftsin analogs are ...

OBJECTIVE Cartilage injury is one of the most common disorders of synovial joints. Fresh osteochondral allografts are becoming a standard treatment; however, they are supply constrained with a potential risk of disease transmission. There are no known virucidal processes available for osteochondral allografts and most methods presently available are detrimental to cartilage. Methylene blue ligh...
